Plugin ISA Version (1.4)
When I download a large file through ISA --> MWG 126.96.36.199.0 (13253), the browser does not show data trickling and progress page,, if I disable Antimalware or use HTTP not problems.
No. Data trickling and Progress pages will not be in the next version, nor any version of the ICAP server.
It cannot. ICAP plays no part in the process. Only the HTTP proxy can control the traffic in such a manner.
I would recommend to use the ISA Chaining plugin instead of the ISA ICAP plugin. It will allow you to use all MWG features, including Progress Pages and Data Trickling. Authentication will be done on the ISA server and the chaining plugin forwards username and group memberships to MWG, so all features should be available.
Where I can download the ISA Cahaining pluggin?
I searched in Https://contentsecurity.mcafee.com, but not found anything, Here are only available Pluggins ICAP.
